Question

The gas arsine, AsH3, decomposes as follows: 2AsH3(g) ⇄ 2As(s) + 3H2(g) In an experiment at a certain temperature, pure AsH3(g) was placed in an empty, rigid, sealed flask at a pressure of 398.0 torr. After 48 hours the pressure in the flask was observed to be constant at 493.0 torr. Calculate the equilibrium pressure (in atm) of H2(g). Then, calculate Kp

Step 1

Initial pressure of AsH3 = 398.0 torr Change in pressure for AsH3 = 2x (from the balanced chemical equation) Equilibrium pressure of AsH3 = 398.0 - 2x torr Show more…
